DMOS delivers dramatic performance gains to LDO regulators

摘要

LDO REGULATORS WITH PNP PASS ELEMENTS NEARLY OBSOLETED THE EARLY NPN LINEAR REGULATORS. CMOS TECHNOLOGY BROUGHT FURTHER GAINS VIA PMOS LDO REGULATORS. NOW, N-CHANNEL LDO DEVICES, WHICH USE BCDMOS TECHNOLOGY, OVERCOME THE PRIMARY LIMITATIONS OF EARLIER DEVICES.
